:innesca To all whom t may concern Be it known that ll, UGUs'rUs Bowser,a citizen oit the -United States ot America, and resident ci' `lloretlWayne, in the county of Allen and State or" indiana, have inventedcertain new and useful improvements in Apparatus for Handling Liquids,of which the following is a specification.

'lhis invention relates to improvements in apparatus lier handlingliquids, and the object thereof is to provide for the safe distributionin buildings and other places of liquids, especially those. that areindanr Inable or otherwise dangerous, and to edect the distributionunder air pressure thro-ugh piping' which leads troni a storage tank tothe place of discharge, without danger of unintentional flow of liquid.

rlhe object or this invention is accornplished by the constructionillustrated in the accompanying drawings in whichy Figure 1. is avertical sectional view of a building with the invention installed; lig.2. is a detail view showingn the controlling apparatus partly out awayand in vertical section; llig. 3. is a transverse section oit Fig. 2. onthe line X-X; Fig. 4f. is a detail showing a clutch used in theapparatus; and Fig. 5. is another view ot the clutch, parts being shownin section on the line Y-Y of Fig. 4t.

'Similar numerals of reference indicate corresponding-parts throughoutthe several views, and referring now to the saine: 1 is a building,1 and2 is the door thereof.

3 is a pit separated from the building, and 4l isa storage tank forliquid located en` ternally ot the building; and below the door levelthereoit'. 'llhe bottom ot' the pit eirtends below the bottom level ofthe storage tank, and contains an auxiliary tank 5 that is connected atits lower end with the storage tank 4 by ineans of a pipe 5. A checkvalve 7 is arranged in connection with the pipe 6 between the auxiliaryand storage tanks and is adapted to prevent back tlow ot liquid from theformer tank into the latter. Hand operated valves 8 and 9 are alsoarranged in connection with the pipe G, one on either side of the checkvalve, and are intended to be closed when the check valve is beingrepaired and when the apparatus is not being used..

kn open vent-pipe 10 leads from the top of the storage tank so as tomaintain therein atmospheric pressure, and the storage tank hpccilcationof Letters :Patent .application 'filed March B, 1910.

has also a spout 11 through which it is charged with liquid. 'llheauxiliary tank 5 has a discharge pipe 12 leading from its lower end, andextending above the floor level in the building where it connects withthe discharge apparatus A, .and this-discharge pipe has an extensioandconnecting with a closed expansion tank 111 llocated above 'thedischarge apparatus. The auxiliary tank becomes filled with liq uidtrointhe storage tank by gravital flow, and the liquid received int-o theauxiliary tank is expelled therefrom by air pressure that is introducedinto its upper end through the air pipe 15. Vllhe upper end of the airpipe 15 communicates with the cont-rolling valve 16 which is ot the twoway type otx any suitable construction. rlhe valve 16 has in connectiontherewith a vent pipe 1'? and an air supply pipe 18, the latter beingconnected also with avsuitable source ot air under pressure as with atank 19. 'lhe valve 16 is operated by its stem-Q0, which when properlyturned, causes air from the tank 19 to enter the auxiliary tank 5through the pipe 18, valve 16 and pipe 15, and when the stem is returnedto its opposite position, the air in the auxiliary tank will'becornereleased and discharged through the pipe 15, valve 16 and ventpipe l?.1When the air is thus released troni the auxiliary tank, the latterbecomes refilled with liquid by gravital flow from the storage tank 4i.When air is forced into the auxiliary tank, the liq-l the liquid to risein the pipe 12 to the level of the discharge apparatus ik, but preventsany discharge of liquid except through the discharge apparatus.

'Ehe grease cup 21 has connection with the valve i6 through the sideport 22 and is tor the purpose ci lubrication.

The controllingm valve 16 and the discharge apparatus proper, torconvenience, are contained together within a case 23, and the dischargeapparatus proper consists of a' cylinder Q4 having therein a treeplunger 25 which is adapted to be moved therein reciprocally from oneend ot the cylinder to the other. A three way valve` 2G is arrangedwithin the case and has at its opposite sides connections res ectivelywith the correspondingl ends 2 and 28 oa the cylinder Qa hy rneans olpipes 29 and 30, rlhe valve 26 13 leading to has also at its top adischarge spout 31, and

'which has the eii'ect o'f expelling the contents of that end of thecylinder out throu h the valve and discharge spout 31. When t e valve isturned to its opposite position, the liquid in the pipe 12 enters thelatter end of the cylinder and returns the plunger toward the former endwhich has the eect of expelling' the liquid previously admittedtherelnto, out through the valve and discharge pipe 31. When the plungerreaches one end of the cylinder or the other the flow of liquid isthereby stopped until the valve is again turned. Thus, a limiteddischarge of liquid throug the discharge apparatus occurs with eachoperation of the valve.

Upon the operating valve stem 2O is fixed a clutch 33 having springpressed lugs 34 which are adapted to engage' the abrupt ends ofcorresponding lugs 35 extending from a toothed wheel 36, the latterbeing loosely mounted upon the stem 20, so that when the stem is turnedin the direction indicated by the arrow Vthe wheel 36 will be likewiseturned. When the stem is turned in the opposite direction, the lugs 34Vslide upon the tapered sides of the lugs 35 and are thereby pressedinwardly and become ineffective in turning the wheel. Upon the stem 32ofthe valve 26 is fixed a toothed wheel 37 of like proportions and inline with the wheel 36, and a sprocket chain 38 connects the two Wheels,so that as the one is turned the other will be turned accordingly. Inthis manner the valve 26 is actuated w en the valve stein 20 is turnedin the direction of the arrow. Stops 39 and 40 extend from the case 23so as to engage the handle 41 on the stem 20, and the stops are locatedrespectively so as to allow approximately a hal-f revolution of thehandle. The handle is held in lowermost position by meansvof aretracting spring 42 which winds upon a segment 43 fixed upon the stem20, when the latter is turned in the direction of the arrow. In thedrawings is shown check controlled apparatus in connection with thedischarge apparatus, although such is not essential to the operation ofthe present invention. The apparatus shown consists of a notched disk 44fixed upon the stem 32, which is locked by a pawl 45. The pawl isintended to release the disk upon introduction of a checkl in the way46, so that the stem may be turned. This feature may be omitted or asubstitute mechanism applied without constituting a departure from thisinvention.

In the operation of this invention, the tank 4 is charged with liquid,and the pipe 18 supplied with air under suitable pressure from anysuitable source of supply. The liquid in the tank `4 gravitates throughthe pipe 16 until the auxiliary tank 5 and pipes 12 and 15 have beenlled to the level of liquid in the tank4, this constituting the normalconditionwhen no liquid is being drawn. When the handle is turned up thevalves 16 and 26 ,are both turned and air from the pipe 18 passesthrough the valve 16 and -pipe 15 into the auxiliary tank and forces itsliquid contents out through the pipe 12 o-n through the valve 26 intooneend of the cylinder 24 and drives the plunger toward the opposite endthereof, thus forcing the contents of the cylinder before the plungerout through'the valve 26 and discharge spout 31. When the .plungerreaches the end of its stroke the flow of liquid ceases, and thereforethe quantity of liquid discharged at this operation amounts to no morethan that previously contained in the cylinder ahead of the plunger. Thehandle is then returned to its lowermost position, in which event thevalve 16 only is turned, which allows the air previously admitted intothe tank 5to escape through the pipe 15, valve 16 and vent pipe 17. Uponthe release of the air from the tank 5, it becomes replenished withliquid from`the storage tank as before. When the handle is again turnedup, the position of the valve 26'is reversed so the liquid expelled fromthe tank 5 will e'nter the end of the cylinder oppositely from that inthe previous operation, and the plunger will correspondingly be driventoward its former position, expelling the liquid previously admittedinto the cylinder out through the valve 26 and discharge spout 31.

lVith this apparatus a limited quantity of liquid is discharged uponeach complete operation of the handle, and the discharge of largerquantities by accident or carelessness is prevented.
